Diet, ADHD & Behavior
A Quarter-Century Review
A report by Michael F. Jacobson, Ph.D., and David Schardt, M.S
This report reviews 23 controlled studies of the effect of food dyes and other dietary constituents on the behavior of children with Attention-Deficit/Hyperactivity Disorder (ADHD) or other behavioral problems. Though the studies are limited due to the number of subjects, extent of dietary changes tested, assessment techniques, and other factors, 17 of the 23 studies found evidence that some children’s behavior significantly worsens after they consume artificial colors or certain foods, such as milk or wheat.
